Technically, you could probably say that fans engage in “Twitter battles” during every game of the season. In fact, people who hold a rival team in particular distaste rarely let the league’s schedule makers determine when they’ll launch their insults. Sometimes the results are charming and amusing; other times it gets ugly or downright creepy. Then again, that’s the danger and delight of the Internet: it opens up all kinds of avenues – not all of them are good, though.

Fans can enter a tweet that includes one of two hashtags: #GoLAKings or #GoNYRangers.

Fans who use the #GoLAKings tag will be entered in a drawing to win a free round trip ticket via Delta Airlines. (Delta will fly anyone to one of their destinations in the United States or Canada.)

The Kings will donate $1,000 for every 5,000 tweets to the Children’s Hospital in Los Angeles.

It’s unclear what the Rangers are doing for fans who go in their direction, but it’s likely that charitable organizations would benefit from their side as well. (Feel free to share the Rangers’ plans in the comments.)

In the spirit of the situation, it would be ideal if fans kept their tweets clean. Example: avoid controversial subjects like the two franchises’ battle to land Brad Richards and stick to common ground issues, such as communal mockery of Sean Avery.
